when I graduated from high school I got a very good job offer, at that time I turned it down with the excuse "maybe it's not the time" and I felt "I'm afraid I can't do well", basically a lot of stupid fears that I ended up not accepting the offer that, and 3 years later I just realized that my mistake was not daring to start / try it first before rejecting it.
it was a big mistake i have to admit.
So sad you missed that opportunity to your fear of the unknown but it's all well and good, you've learnt and I think that's what matters now.
👍👌.
The most important thing you need to learn is believing in yourself and your abilities. Also even though they are things above you, then you should learn to challenge yourself!
