I have been lurking on this site for a while and have yet to post. All id like to say is that if you commit yourself to something you can have amazing results. I've done some things in my life that I thought I couldn't because i didn't have the knowledge or training or skill. Turns out all I needed to do was commit and stay focused and I was able to achieve my goals. If people walk around and believe that it takes someone special to do something then they will problably never achieve any of there goals. Also if you don't ever fail then you aren't setting high enough goals to unlock your potential. Good luck to you in your venture and I hope you get where you want to be!
All true. On the flip side, you always have to weigh the costs of going for something (financial, health, family, emotional, the time investment, etc) as well as all the things you will have to lose out on in the process and the things you will have to sacrifice and the other opportunities it will cause you to miss out on against what you potentially stand to gain if you achieve that goal. Then you have to assess the realistic probability of actually being able to achieve that goal if you do go for it. When you factor in all the costs and potential costs of going for something, the potential gains if successful, and the realistic probabilities of success, sometimes it is becomes clear that you would have to be an idiot and a fool of the highest order to go for it.
I'm speaking in general here, not just in regard to the OP's quest. The whole "go for any goal at any cost" is reckless and rarely works out well, and the whole "you can succeed at anything you want to" is nonsense and simply not true. Both of those sentiments have been uttered repeatedly by you and others in this thread though. We need to stop living in a feel good, tell people what they want to hear instead of the truth, make believe, fooling ourselves, pretend world and actually start living in and dealing with reality. That means weighing costs against potential gains and accurately assessing probabilities and making sound decisions accordingly, not decisions based on fairy tale land feel good sayings.
To be clear I am not saying we can't achieve more than we or other people believe we can at times if we push ourselves. Often we can. What I'm saying is you still need to be realistic about things and and use sound judgement and "go for any goal you want at any cost" and "you can succeed at anything you want" are neither realistic nor sound judgement.
