Be in your own corner, fight for yourself, and never forget to give yourself another chance.
Because life gets in the way, because people don't always tell us (or recognize) how vital we are to each other, we don't always know that whatever it is we bring to the table is something the next person may need to do his/her own bit at work, at home, or in the world.
It's a new day of a new week, so do me, and you a favor: practice being good to yourself. Learn from the bad stuff but don't keep beating yourself up over it. You did it, it's done. What next? Fix it and don't make the same mistake again! Sound simple, right? Try it, and let me know how it goes for ya, and I'll do the same :)
