Apologies for any typos.
No it doesn't make you dumb, it means you have not found your niche to create an "_app'_" to take on and maybe even excel at compared to your peers.
It also means that you probably have much more activity in other fields in your private life which would make you think a lot.
I found mine in the late 90s:
My programming niche...
This started me on the road to my multi language learning.
I hadn't ever seen a shell script until joining this site in January 2013 so I jumped in at the deep end bragging with an AudioScope.sh, a SINGLE "bash" script which has, and is, still being gently followed.
I deliberately placed limits on it and the biggest one was the I/O. ONLY the mic and ear are allowed for input and output. USB, Parallel, Serial and others are NOT allowed.
These had to deliver DC as well as AC components on input and output. I got a tremendous amount of help from the big guns on here and from these beginnings I have done some really strange things and most are POSIX compliant:
A DFT in a PURE ksh93 shell script.
A GOTO function.
A Fixed Point SQRT using integer maths.
And much more, all on this site. Most have been bettered by my peers who still know much more than I do about UNIX scripting.
Why?
As a pure learning task to see if it is possible and nothing more.
I am working on a POSIX compliant DFT using integer arithmetic ATM and it is seriously tough. I don't expect it to work but I do have a natural ability to think laterally/orthogonally hence my bizarre uploads to this site.
So GO FOR IT, even if it is something like a CrossStitch Program or calculating the minimum area for a _mains_ cable carrying large current loads.
You would be surprised what you learn by taking on such a task.

I pass on this one. My brain is not made for programming. Though I think I can handle pretty much everything else pretty well, and I am now nearing 34 years working in various fields in IT, I just pass on scripting on everything longer than a very long one-liner. Not for lack of trying. I do understand scripts in various scripting languages well enough to debug them, to adjust them to my needs and to expand them if necessary. But I could not write one on my own if my life depends on it. Does this make me dumb?

sh
sh(1) General Commands Manual sh(1) NAME
sh - Shell, the standard command language interpreter DESCRIPTION
[Tru64 UNIX] Tru64 UNIX provides two command interpreters with the name sh. The XCU5.0 and POSIX.2 compliant command interpreter sh is available in the file /usr/bin/posix/sh and is described in the sh(1p) reference page. The Bourne shell, historically known as sh, is available in the file /usr/bin/sh and is described in the sh(1b) reference page. [Tru64 UNIX] Your initial, or login, shell is determined by your entry in the file /etc/passwd. This file can be changed only by your sys- tem administrator. You must use whatever procedures are in place at your location to have this entry changed. [Tru64 UNIX] If available on your system, you may use the passwd -s or the chsh commands to change your login shell. Note This option is not available if your site manages passwords through the Network Information Service (NIS) facility. Check with your system administrator. [Tru64 UNIX] Subsequent shells spawned from the initial shell depend on the value in the environment variable BIN_SH. If this variable is set to xpg4, the POSIX shell is started. If this variable is set to svr4, an SVR4 compliant version of the shell is started. If this vari- able is unset, the Bourne shell is started. If this variable is set to any other value, an error is reported and the results are unpre- dictable. See the EXAMPLES section for information on setting this variable. NOTES
[Tru64 UNIX] With Tru64 UNIX Version 4.0 the Korn shell, /usr/bin/ksh is the same as the POSIX shell /usr/bin/posix/sh. RESTRICTIONS
[Tru64 UNIX] The file /etc/shells must include entries for both the POSIX shell /usr/bin/posix/sh and the Bourne shell, /usr/bin/sh. If this file is incorrect, see your system administrator. EXAMPLES
Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the POSIX/ XCU5.0compliant shell, enter: BIN_SH=xpg4 export BIN_SH Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the SVR4 compliant shell, enter: BIN_SH=svr4 export BIN_SH Using the Bourne, Korn, or POSIX shell, to unset the variable BIN_SH, enter: unset BIN_SH Using the C/ shell, to set the variable BIN_SH to use the POSIX/XCU5.0 compliant shell, enter: setenv BIN_SH xpg4 Using the C/ shell, to set the variable BIN_SH to use the SVR4 compliant shell, enter: setenv BIN_SH svr4 Using the C/ shell, to unset the variable BIN_SH, enter: unsetenv BIN_SH FILES
