There is no overnight transformation physically or mentally. It takes determination, consistency, hard work, patience, eye on bigger picture, self-control, growing through the difficulties and growing stronger and stronger.
Set yourself in motion, take those first steps, make mistakes, learn, practice, improve, keep an eye on goal but focus on the process, be consistent, do not give up, be patient and keep going. Results will start to appear only after relentless effort for sustained period of time. Key here is to enjoy the journey and believe that amazing things always take time and it is worth the effort.
