It's better than over analyzing what you want to do.
You know what happens when you start over analyzing something? You stress yourself out. You wear yourself out, you worry, you over think, you make stuff up in your head, and you over exaggerate. What an imagination our brains have! But seriously speaking, there's only so much analyzing you can do. At some point you're going to have to kick your ass into gear. At some point you'll have to put the key in the ignition, start the engine, and push the pedal. You can't do that with your mind.
Procrastinating won't get you anywhere.
Getting started is easy, simple, and doable. Yet procrastinating is also easy to do. Ironic isn't it? But the truth is, delaying what you've been dying to do isn't going to benefit you. At best, it'll hinder you in more ways than one. Remember what I said earlier about what we do everyday is a habit? Well If you procrastinate enough, that habit will creep into other parts of your life as well. If you procrastinate with simple things, you'll procrastinate with harder things. One leads to another. Start small If you must, but at the least you need to get started.
3.The last thing you want to do is regret not starting.
Regretting what you've done is one thing, but regretting what you've never done is another. Lets be honest, regretting what you haven't done is so much worse. Especially when it's something you're adamant to do. You don't want to be that person who regrets it 30 years from now, do you?
You can adjust your actions along the way.
Ready, aim, fire! You've heard of the saying, right? Well what happens if you spend all your time aiming, and not firing? You'll never hit anything! That's basically what you're doing by thinking too much and not getting started. Ready, fire, aim should be your approach. You might not get it right on the first shot, but you can adjust your aim as you go along.
It's better to make a mistake than do nothing at all.
This ties in with the last point I just made. I don't like to make mistakes, you don't like to mistakes, nobody likes to make mistakes. But nobody's perfect so it's impossible not to make a mistake. As great as computers and smartphones are, even they can make mistakes! You can't get away from it. And that's OK. Just be sure to get started on whatever you've been delaying for so long. And when you do make a mistake, learn from it and get it right the next time. Then you'll be way ahead, I can guarantee you that!
