All self-improvement starts with self-reflection. Know thyself is the starting point for all self improvement. You have to understand your strengths and weaknesses and understand the personality you need to develop to be successful.
The next step is to have specific short-term and long-term goals. The normal long-term goals for self-improvement relate to the following categories:
Career
Social status?
Education and training
Physical well being
Earning and saving
Your objectives will depend on your goals.
E.g. If your goal is to be promoted to office manager in two years, then your objectives will be:
Learn basic principles of office management
Receive good report from the boss
To train for your promotion, it is important that you take an inventory of your knowledge and skills. Check what you are lacking in and start building on the required skills.
