You may make the wrong turn in life and it leads you to a dead end. Luckily in life U-TURNS are not ONLY allowed but they are a natural part of life.
You shouldn't be so hard on yourself that you chose a path that unfortunately led to nowhere.
Not only do things change over time that determines where a path leads but as humans we change over time and where we want to be, also changes.
What worked in the past may not work anymore. What worked for someone else may not work for you.
Adapting to life is necessary to go with the flow. Doing a U-TURN when you hit a dead end is necessary to keep moving in the right direction.
If you get knocked down in life you got to get up, dust yourself off and get started again. It doesn't matter how many times you have to "start over" all that matters is that you get up.
Remember in life U-TURNS are not ONLY allowed but they are also necessary at times, that's just LIFE.
