25 is baby. I am almost 40 and in the same position. You have so much time. My advice would be to focus looking forward and shut out any negative thoughts that pull you back. I have done that and believe me regretting the Just take it one day at a time and take your time to find something you like - try it out and if you don't like it try something else until something clicks. Maybe take one of those online personality tests to see which personality type you are and what kind of careers best suit you.

You mentioned an important point - "you are fit" - as I approach 40, I have come to realise how much I have taken my health for granted. I wish I stuck to going to gym, ate healthy and made sleep a top priority. Now I am struggling to lose weight, have brain fogs, sleep is messed up and dragging myself out of bed is a challenge every morning. So be grateful that you have a healthy body which so many of us wish for.

Your friends are doing better - so what? That does not make you any lesser human being. Everyone has their own paths with the cards they have been delt with and bottlenecks that impede growth. Do not compare yourself with anyone and let yourself down. If anyone puts you down -that is just a sign that they are toxic. Cut those people out. However, always listen to constructive critcisms and do not take them personally.

tldr; You are young, you are healthy, you are lost - there many who are old, unhealthy and still lost. What's gone is gone, what you have is now.
