<p>You have to try acknowledging the fact that failure is a possibility. Absolutely nothing in this world has a guaranteed 100% success rate, except maybe dying after 100 years. In any kind of a situation, there are going to be people who are successful and people who are not. Can you imagine how good it would be if you succeed, and how bad it would be if you failed? Next weigh your chances, you say you don’t know, but do you mean the chance of success and failure is 50/50, 60/40 or more like 90/10?</p>
<p>Now ask yourself how much effort you have to put in. Are you doing 20 hours of work per day to try and succeed? 4 hours? half an hour? Then ask yourself the ultimate question: given how good it would be to succeed, how bad it would be to fail, and the chances of each, am I willing to put in the amount of effort I am now to continue to an outcome? If you’re not feel it’s worth it, don’t continue because it won’t be worth it, obviously. (Talk to others like friends and family about this too, to get perspective about your chances and prospects).</p>
<p>If you feel like not continuing, why not lower that goal to something more manageable? Say my goal now is to make Harvard my safety, but figure err, that’s ridiculous. I might decide to settle my goal on making my state flagship my safety instead. This makes the chance of success much higher, which proves to be worthwhile to keep putting effort.</p>
<p>Some people choose goals that are challenging, as in it will be a gamble to see if they succeed (reaches anyone?). If you do succeed knowing there is a chance, your success will just feel so much better. Nothing stops you from choosing an unchallenging goal with 90% success rate however, but that’s just not very exciting. Hope this helped.</p>
