If it’s got to be done, then do it now.
If there’s something pretty fundamental that I’ve learnt, it is this : If you want to get something done, do it now. If you wait, chances are high it won’t get done.
You can’t wait for it to take place contingent on some occurence – that is very risky and it takes the whole issue out of your hands. Any decision about whether to do something is now resting on some external factor, which you are not able to control.
You can’t wait for a point in time. If you’ve decided that it has to be done, there’s no time like the present.
Start now. Assuming you’ve taken this long to make your mind up about whether you need to do this, chances are high that the littlest thing will bring about failure. So starting early will give you time. Time to fail. Time to learn. Time to restart.
