The constant need within our brains to get better is exhausting sometimes as it’s so much work to stay positive. On the other side of the fence though is the constant thoughts of just throwing in the towel, so much easier. Classic good vs evil battle reoccurring daily right here in our own heads. The good news is if you have that need to always improve you have the will. Now you just need to fold that towel up, put it back in the drawer and get to doing. 
Have a great Sunday!
