Listen to your body

Ask yourself before asking others. Most times the answer lays within us, cause the person who knows you the best is YOU!
With that said, asking for advice from others is sometimes helpful,  but choose a few people you trust rather than ask for everyones opinion.

Set guidelines

Guidelines will keep you on track. No matter how busy you are at work or in life in general, having guidelines will help you to stay balanced and to make you do the right decisions. 

Note: make sure you understand these are guidelines, not rules..
