We must have complete faith in God or your master or teacher. God can be considered as our Master. 

We must put in our best efforts in whatever we do and leave the rest to Him; hold on to Him. Then, He will take care of us and do what is right for us, and thus, we will be able to handle trial and tribulations better and be saved from any trouble.
