Someone or something will get in your way as your push towards your goals. How you react is up to you. You cannot control what others say or do but what is in your control is your reaction. Winston Churchill stated it perfectly, "if you are going through hell, keep going". The fact of the matter is it does not matter what stage of life you are in you will go though hell. Applying for PT school and getting rejected was awful. Making it through PT school in many ways has been ridiculously hard. Facing on a daily basis an opponent to my moral was shear hell. Whether it is a friend, a family member, a professor, a clinical instructor, or even an institution pushing your down; don't let them keep you down. When you get knocked down it sometimes it takes a minute to get up but get up and brush it off. Re-evaluate and re-establish your goals and go for them. I have recently come off of an experience where I was told I will never make it. I was told I will not be successful PT. This person day in and day out for months would slowly tear me down. I started to believe them; I'm not good enough. I won't pass my boards. I'll never be a successful PT.
The only thing I can do is move forward and prove them wrong. Not only will I be a good PT but I will be a great PT. At the end of the day I have goals and I must keep moving forward. Remember there are detractors but there are those who have a hand extended out to help you up.
When you get knocked down, get back up, and keep moving forward.
