Back when I started out, I used to worry about every little detail and take things personally. If something didn’t work out (a deal that fell through, for example), I’d spend lots and lots of time thinking about it.
I’d get mad at the other party.
And/or start blaming myself.
Simply put, I treated each failure as some kind of an insult.
In retrospect, this all seems foolish but at that point, these things made me waste a lot of time/energy.
As time passed however, I ended up understanding that there’s only one way to be 100% certain you won’t deal with failures: isolating yourself from the world and not doing anything. After all, the only surefire way to avoid failure is not trying anything in the first place.
But we can’t have that, can we?
The bottom line is that if you’re ambitious and try to make things happen, you’ll inevitably screw up (in some cases royally) every once in a while. Or maybe you won’t screw up but instead, the other party will do something that’s not exactly fair.
These things happen.
To the best of my knowledge, there’s no such thing as a road that leads to a worthwhile destination which isn’t bumpy every once in a while. You’ll gradually end up understanding that there’s absolutely nothing to be ashamed of when it comes to failure.
Even more so, you might realize that the journey itself is far more important than any of the destinations.
Just do your best, be ambitious and don’t take things personally.
If something bad happens, have a healthy attitude towards the situation in question. Ask yourself what you did wrong and what the lessons you should learn from it are.
Something bad happened, you learned some lessons and moved on.
Dwelling on these things even one second more than you have to just isn’t worth it. In fact, it’s a surefire way to lose what little sanity you have left… not all that much in my case but maybe you can still be saved
