Life is full of unpleasant surprises. These actions are beyond our control. Still, the outcome is largely determined by our reaction.
When bad things happen, you could complain. This will do nothing to solve the matter, and causes unwanted frustration. Telling others will only result in them nodding their heads and tuning you out.
Instead, take an honest look at the situation. Determine if it can be salvaged or you should start over. When the end has been reached, begin anew.
Weigh the advantages and disadvantages before taking action. Often, it is not about what is right or wrong, but what will produce the best results. If your heart is flawed, the mind will rationalize.
Fear will be your worst adversary. Doing new things is a scary proposition. It is easier to go with what you know.
The world changes, though we wish it would not. That is why adaptation is so important. Either the current drags us under, or we learn to ride the waves.
