Every wrong turn I took became part of my experience, had I not made those mistakes, I'd probably make them in the future or forever wonder why I didn't do what I did. Some of those choices were brutal and nearly left me on the street with nothing whereas other decisions ended up being awesome decisions that made life so much better.
Even in those dire situations, which could have been avoided had I made different choices, I learned new skills which opened many doors for me years later.
As they say in the business world, the rearview mirror is always clearer than the windshield in front of you - the same goes for careers, looking back, I could have done a lot of things differently, but then I would not have gained all the experience that I did.
