There are many tips for self-sufficiency and it's a challenge that should go through one life. Where you start depends on where you think you want to go. Sometimes where you think you want to go may not be where you end either.
First, try to determine your goal. Write down a dream life of everything you think you want or want to be. From this list of goals, divide them into those that you can achieve in the short term, middle and long term. Then think about your goals, are they self-centered or others centered? Divide the lists into these subcategories. Sort them in order of priority. If you want to see fast progress, put them to make it easier for you to gain strength and positions from accomplishing tasks. If you put them in the order that is important to your life, they will probably be the most difficult one on the list and will take longer to reach. You need patience and perseverance for them. Now, select one or two of the top in each list, and that's the goal to start with.
Next to self-improvement tips, make a short list of self-determinations that you can put on the bathroom mirror so you can tell them aoud several times a day. Do it daily. As you say, see your own or have them. Over time, we will gradually take care of the improvements.
Look at your body style. Are you eating the right, quiet food? Are you practicing at least twice a week? Are you and your clothes neat and clean, in other words, concerned? Or are you bad and careless? Put some effort into caring for yourself and your environment. Messy life will lead to messy minds and emotions. If you eat properly, you'll feel better about everything, be healthier and live. If you are proud of your appearance and at home, you'll feel happier there, organized to handle the list of goals.
Try to study something new, read books or magazines, or learn something in class or independently. Having real knowledge about individuals brings more confidence in your life. You can practice something like a device or game and gain confidence in that way. All of this will improve your confidence.
Two final tips for self-esteem are laughing and helping others. Good laugh can actually improve your health and a lighter look at life will also help you feel better about yourself. Helping others is even better than doing for yourself. You are confident and aware that you make a difference in your life. And you are!
There are many tips for self-sufficiency. Some are tasty like food and health, others are more vague, like self-confirmation or helping others. They build all your identity, and it's self-esteem.
