You don’t have to quit your job, dump your “other”, or move far away to change your life. You don’t have to wait for your kids to go to college to reclaim your life. You don’t even have to change your look to get a fresh start. Waiting, worrying, and woe-ing will get you would haves, could haves, and should haves and before you know it, you will have wished your life away.
If you want today to be different, then do things differently. Think about things differently.
Otherwise the same patterns will reappear at your new job, with your new love interest, or in your new city. The old attitudes will not have moved out with your kids. And certainly, the same opinions of yourself will greet you at the mirror.
If you want today to be different, then be different.
