It's amazing how much time we spend thinking about the possibilities of doing things instead of actually doing them.
Just pick one thing you have been really wanting to get around to doing "one day". How many hours have you spend thinking about the possibility? How much time and energy have you spent talking yourself in and then out of it? How much energy have you invested in the "maybe"?
If we turned that energy around into actually DOING it, we would be well into it by now. Sure, there's risks...that's what life is about. Would you really rather be safe and unsatisfied, or find freedom in actually doing what you feel drawn to do?
We pend so much time wishing we could be somewhere/someone/doing-something else, that we have forgotten how to go out there and create our own reality, invent our own future, and take charge of our own destiny.
It's in our genes to go out and take risks, to chase down the scary beast with nothing but a spear to feed the family. It's a rush, an adrenalin pumping high, which excites us, makes us run faster, leap further, take ourselves to new highs we have never been to before. It makes us shine.
Go on, go ahead and shine. Take a leap, and make it happen. Isn't it better than sitting here just thinking about it?
