If you are the sort of person to set goals or accomplish things then the task can often feel quite overwhelming at times. I remember when I sat down for my first lecture for my part time business law degree. It was the start of a five years study in the evenings.
Here is how I got through it.Everything can be chunked down into bite sized pieces. I knew that each module was a year long and was broken down again into one coursework and one exam. All I allowed myself to do was to focus on each assignment and nothing more. if I had to dwell upon the 20 other exams then I would feel overwhelmed and choke.
Same for my black belt. One belt at a time split six months apart. Each belt broken down into three training sessions per week with a seminar every two months. I started as the person closest to the door at the back and slowly worked my way up the lines until one day, it was me at the front. Everyone else had quit or moved on.
Take whatever goal you want and chunk it down into steps and then dwell only upon the next step you need to take. This works for business, making money, passing exams, losing weight or pretty much anything in fact.
Have a go.
