I used to feel like that. Now I can enjoy my hobbies and interests even though I am not the best.
One thing that helps with dealing with this is to become more discerning. Many people seem good but their work is in reality entirely without substance. Very few people manage to do anything that is anywhere near what could be considered truly great, let alone worth anyone's time at all.
A lot of stuff that looks great at a glance falls apart completely under scrutiny. The few people who are truly great at something should become inspirational rather than jealousy-inducing for you.
Great works are lifefuel the way I see them, they can be studied to an infinite depth just like whatever interests you have. You need to view your self-worth as inherent, you can't let it hinge on how good you yourself think you are at something, or even worse: Based on approval from others.
Hobbies and interests are supposed to be fun after all, and if you are truly interested in something you will find it infinitely fun to keep learning about it, no matter how good you are at it. Do not be afraid to have several deep interests as well. Everyone having to be a specialist is a PsyOp. Hobbies and interests are not some purpose for life, they are merely high quality COPES. It is not something you should judge your own "worth" upon in any way. Your hobbies and interests should be stuff you would enjoy doing even if you were Chad.
Talent is a real thing, and us truecels generally do not have a talent for anything which can indeed be very frustrating. But it is a blessing to have an interest in something. Too many people do not even have that. People might call this cope, but I believe that people without a natural givenness for something have more to gain in an interest than people with talent.
Even basic competency in something will be hard-fought. You will likely hit your limits quite quickly as well. But limitations breed creativity. And you will likely go deeper into understanding something than someone with talent.
A lot of truecels are lucky to have a lot of time as well, time that can be entirely taken up by an interest since nothing else is going on in one's life. And like I said, when you are deep enough into an interest you will not care if you are good or bad. It will not hinge on approval from others either.
Lastly, and most important of all: Remember that nothing is truly original. No human is the sole genius creator behind anything, we are merely conduits to what is adjacently possible. Once you realise that nobody has any ownership or lay to claim anything at all, what other people have managed to do in comparison to yourself will no longer feel so special.
If you have never seen it before "Amadeus" is an excellent movie about this very subject.
