3. We all have our own path to follow in life. Don't compare and don't judge.
In this life, we all have our own lessons to learn and obstacles to face. Even if we face similar problems to others, the circumstances are always different. There's nothing wrong with that, sweetheart. We grow and evolve and change in our own way and in our own time. The key is not to compare your path to anyone else's. It is yours and yours alone. It was specifically designed for you. It will shape you and mold you into the person you are supposed to be.
You may learn a particular lesson at 20 years old, that someone else doesn't learn until they are 40. That doesn't mean that your life is harder at 20 than theirs was. You are just facing different obstacles at different times in your lives.
Which brings me to another important point: As easy as it is, we shouldn't judge others for how they face their obstacles and travel their own path. Again, their problems may seem similar to something we've faced, but the circumstances are always different and the lesson they are supposed to learn may very well be different from the lesson you were supposed to learn. The right thing to do for them at that particular moment in their life, may not be the thing that would be right for you. That doesn't make it any less right for them. Let them follow their own path.
