This is something that many will not be able to comprehend base upon their inability to know their worth. Honey let me tell you, don't place value on time wasted but more so on the lesson that it taught you.
You can't get far if you're constantly putting other people needs ahead of your own. Accept that it's not involuntary. You open the door and allowed yourself to be taken advantage of. The key to getting your mind in order is to understand that the mind is a muscle. You have to learn how to exercise it. Observation is vital to your growth. Pay attention because seeds of thoughts are planted throughout your life. People shape and mode your perception as to what should be. Recognize that there is a cause and effect towards everything. When you're at a fork in the road , An easy way to choose the right path is to remember that you made the choice. Thank you @justrobsworld
