1. Overcome Your Fears
Everyone has fears, but how many people actively seek out ways to overcome them? If there's a fear you've had your whole life, or even for a while now, there's most likely going to be a way you can overcome it if you really want to. No one wants to live their life in fear, so now is a perfect opportunity to overcome some of your own fears before they (possibly) stand in way of you living your life.
2. Focus on Your Health
No matter how you've lived your life so far, it's never too late to adapt to a healthier lifestyle and make your health something that you focus on. This doesn't mean just having a healthy diet, lifestyle, regular exercise etc., but also ensuring you have a positive mindset and emotional stability. The thing to remember here is to focus on both your physical health and mental health equally.
3. Challenge Yourself Regularly
When was the last time you pushed yourself to achieve something new or something you really wanted? Recently, I hope! Despite how difficult it is for some people to do, finding ways to challenge yourself as well as to push yourself are both great habits to get into. Get yourself outside of your comfort zone, as strange as it may feel sometimes, and enjoy experiencing something new and unfamiliar to you.
4. Ask for Feedback
Many people might not even think to ask for feedback a lot of the time, but you would be surprised at how much good it can do for you. First of all, you need to be ready to hear the truth and comfortable receiving constructive criticism as well as the good things like praise and positive encouragement. This is especially a good idea if you don't know how to start working on yourself; all you need to do is ask someone who knows you well what they think you need to work on and use their answer to draw on for ideas.
5. Avoid Negativity
I totally understand that this isn't always possible, but this is a great habit to get into and it will change your outlook on life if it is and you can manage it. Don't feel bad if you end up having to cut off negative people from your life or distance / remove yourself from a negative situation. Many people believe they can 'handle' negativity, but truthfully I don't think anyone really can without it eventually affecting themselves in only the most negative ways.
6. Quit a Bad Habit
This doesn't apply to everyone, obviously, as many people have already eliminated things like bad habits from their lives or never had to experience them at all. However if there's anything you do which you know is bad for you, it's always worth making the effort to stop and change. I'm not saying it's an easy thing to do, but as long as you're trying to kick it, you should be proud of yourself for taking this tough first step.
7. Stay Committed
Above all, commitment is the key to working on yourself and changing your life in the most positive and meaningful ways possible. If you don't stay committed to these kinds of lifestyle changes, it will be very difficult to go through stages of personal growth and to become a better person in all the ways that you could be. I would be lying if I told you that working on yourself is an easy thing to do and can happen overnight, so remember to have plenty of patience and make it your top priority!
