Nike has a great slogan:

JUST DO IT

But let’s break it down a bit. Here are three reasons why you should “Just do it”.

For the purposes of this article, we’ll define “it” as the life you’ve been wanting to live.

Just do it - Because no one's going to ask you to do it. No one is going to magically show up at your door one day and be like, “OMG! So there you are! I’ve been looking all over for you!” and present your dream life to you on a silver platter. It seems to happen a lot in movies, but that's about it.
Keep doing it - Because after you've summoned up the courage to start, you will find that it’s much harder than you thought. You might get lonely, depressed, and lose motivation. Remind yourself to keep going because no one is going to tell you to keep going either. You need to be your own motivation. Find ways to keep yourself engaged, and just keep doing it.
Don't forget why you’re doing it - After you’ve pushed yourself further than you ever have before, you might feel like there’s still no hope. You might start thinking that it's time to quit. And maybe you should! But before you do that, remind yourself of why you got started in the first place. It could be that you're exactly where you want to be, and you’ve just forgotten why you came all this way in the first place. If after doing so, you still feel it's time to pursue other endeavors, so be it, at least it was a well-thought decision. But you may also find that you will want to keep going. That perhaps, you didn't want to quit, you may have just needed a break, to recalibrate, to get back to your sense and remind yourself why you started doing it.. and then just do it, again.
