Personal development is often the province of aggressive planners. An overly-restrictive plan can be a hindrance to successful personal development, though. Plans need to remain flexible to cope with unexpected obstacles. When strategies prove unsuccessful, plans have to change to embrace alternative ideas. A flexible plan is always superior to a rigid one.
Admit your low-level in the universe. Admitting that you do not know all is the beginning of opening your mind, heart and spirit to the rest of the world. Each of us is but a speck in the whole universe, and we each have so much to learn, understand, know and improve.
Before you can respect others or be judged worthy of respect, you must first respect yourself. If you take care of your own health and happiness, you can then overflow into the lives of your loved-ones and colleagues to lift them up as well. Putting others ahead of yourself only happens once you have found your own identity.
If things get to a place where you cannot handle them, seek help from someone like a therapist. They can help you to cope with your issues by talking them out and coming up with some solutions. It can do you a lot of good to talk to somebody who is not directly involved in your life; it can provide you with a clear perspective.
Personal development starts with leadership. Leadership can be defined in many ways, but most people like to define it as "influence." Take a look at your leadership journey. What events have impacted you the most in your life? How have you changed because of those events? What is your best attribute that makes you a team player? By examining these questions, you will be aware of how you can fit into a team setting.
