No. I’m not.
And probably you have asked yourself the same question many times and don’t feel bad about that, I gotta tell you a secret, I have asked myself this question so many times and not only when I’m awake but also when I’m dreaming.
Take a look at your past, remember all the hours you used to learn and study, all the sleepless nights figuring out things and maybe all that effort wasn’t paid at that moment but after so many years you’re being recompensed for all the effort you put.
Don’t feel bad about it, enjoy the ride and focus on getting even better.
