Resentment only wastes your energy and keeps your creativity suppressed. Instead of resenting what has (past tense) happened, accept what is, and you put yourself in a position to do something about it. You do not always get the results you desire, and conditions are not always what you would like them to be. But you can always accept where you are and then move on.

In fact, the fastest way to move forward is to be realistic about where you are. Take stock of yourself or your situation objectively. Accept and acknowledge what you have to work with, and you'll begin to see plenty of possibilities.

Acceptance of what is does not mean that you're giving in or giving up on where you can go. In fact, by fully accepting where you are, you enable yourself to make positive use of everything available to you.

By accepting what is, you can make positive use of the triumphs and the disappointments (lessons). By letting go of your resentment and anger for what has been, you can put all your focus on the best of what CAN be.

Stop fighting the battles that are already over. Accept what is, and you've already begun to win.

Sometimes the best way to free yourself from a burden is to accept it. Much of the destructive essence of any burdensome situation comes from fighting against it. Once you stop fighting, you can start progressing. If there is a threat, you protect yourself against it. But there is no point in fighting against what already is. When you accept the situation, that is the starting point at which you begin to make the most of it. When you can go beyond acceptance into sincere gratitude (for the lesson learned), you take on a powerful positive momentum.

In short, accept what is, then find something positive about it. Even the most desperate situation has its positive aspects and possibilities. You'll uncover them only after you've accepted that the situation exists. Acceptance is not surrender. It is the recognition of reality. By clearly seeing what is, by acknowledging and even being grateful, you can move things forward toward the way you would like them to be.
