I have some advice for you from my own experience, and how I overcame all this negativity. “Focus only on one thing at a time”.
So.. you just have to start focusing on one aspect of your life. Let’s say you start waking up early. Now the only thing you should do is to no matter what.. just wake up early. Don’t worry about what you have to do after waking up.. like.. should I go for a walk?.. should I do exercise?.. should I start studying?, should I sit in front of my pc.?.
You see, the thing is, it doesn’t matter if you wake up early.. and start playing Fortnite on your pc. The only thing you have to put your focus here.. is to make sure you are awake by 5 am or 4.30 am. (Remember, waking up early helped me to change.. but it can be different for you, so it is ok if you want to focus on anything else).
So eventually what happens is, you start tweaking your mind and body to do one thing flawlessly.. which was so hard to do before.
And to be honest.. when it happens.. that feeling of accomplishment will automatically affect your mood, emotions, feelings.. mindset and confidence in a positive way.
Trust me, this was what I did myself to get out of that rotten mind moody lazy days. My problem was that I was simply wasting my time. I was looking for that secret-magic trick to change everything and become a better person. I looked everywhere, read a lot of articles, watched 100s of youtube videos. But in the end, I came to understand that, the only thing that can make a change is by taking the first step.
I started waking up at 5 am. It was hard, but the next thing I did after waking up, was to watch my favourite TV shows and play games on my pc. Eventually, I got used to it. So I started waking up early.. and it became natural to me. And then. I started doing other things.. I loved listening to music, so I put on my headphones and took a small walk outside. I just wanted to listen to music and go with the flow. But what happened..? I started to love taking early morning walks. It was so refreshing and life-changing. And.. slowly my walking turned to jog, and I started to jog to the nearest beach.
Long story short… 5 months before I was a guy, who woke up at 7.30, and went to work at 8.30. Came home so tired, zero productive, lazy. I was having all those things you mentioned in your post. I was so depressed. I’m still not perfect, but now I’m a person who wakes up at 4.30 am every day, go for a 5k run in the morning, and in the evening. Doing all that intensive work, my body become so fit, and my mind became so crystal clear. Nowadays I feel so energetic, I am not depressed or anxious at any time. It also helped in improving the work-life, I started learning many things, I started a healthy lifestyle. Also, I have more time in my day to day life, to focus on me.
So I just want to say that, I overcame all the shortcoming of my mind and body, by starting to change one small thing at first, It doesn’t need to be waking up early, you can do anything you wish. But you start taking baby steps, and you will eventually change everything to become a better person.
