They say, it's not how you start, but how you finish...
But really, it's how you start that sets the pace and many times decides how you finish.
Whatever you are going to do, try your best to start well. That goes for in school at work or even in a relationship.
Don't be the class clown for half the year and then you try to cram all the work you can for the rest of the year. Don't be a slacker for the first couple months at a job and then try to all of a sudden to become this great worker later.
The key is to start well. It's like when you button a shirt, the first button makes all the difference. I the same way if you get the first button of anything you try in life correct, the rest is much more likely to work out.
Just some food for thought.
