Accountability does wonders. Even throughout the times when you're at the lowest of all lows. Keeping in mind not just that you're someone's role model, but their only proof that some things can work in one's favor is enough to appease even the most illest of "what-ifs".
"And when you want something, all the universe conspires in helping you to achieve it."
I can't even attempt to recall the number of times I've initially second guessed myself when considering to go after something. I believe it's across the board the level of uncertainty we as human beings experience. And this in all aspects of our life (relationships, finances, careers, and mindsets.) However, I think the key point in tackling these personal endeavors is not in luck, experience, or monies; the authenticity of one's character, adaptability, and perseverance in how one approaches items on their personal agenda can indicate how likely one will accomplish things. It is truly "the possibility of having a dream come true that makes life interesting..." Not the recurrent distractions that everyone partakes in while constantly complaining about the said activity, person, or place they willingly gave acknowledgement towards.
