If you're facing a difficult problem in your life, don't be afraid to turn to a group. There are many groups available that can help with almost any struggle that an individual faces. Groups provide a support system of like minded individuals. They increase your potential for success and give you others who you can remain accountable to.
When building a personal development plan, it is important to consider your personal values. If you go against your values, you are shooting yourself in the foot. Instead, work on aspects of your life you want to improve that mesh well with your individual beliefs. This is the best way to make long-term changes.
You cannot make any progress with respect to personal development if you have not outlined a goal or set of goals. For example, you may be wanting to lose weight. Without a goal in sight, it is near impossible to progress or feel like you are making progress. So, establish a goal now.
