It is easy to get stuck in a cycle of feeling down and out of your depths. It is normal to feel this way now and again because it is not possible to be extremely happy all the time. It is, however, possible to do things every day that can increase your happiness and increase your ability to maintain a positive outlook. These could be small things or big things, but they can make an overall difference to your day:
Be kind to people
Being kind to people is an excellent way to make you feel happy because you know that you are doing something that will make someone else smile. Compliment someone's outfit, leave a bigger tip at a restaurant, or leave a happy note on the train for someone to find. These things don't take a lot of effort, but they might encourage other people to do more nice things for each other in the future, and one day it might come back round to you.
Forgive people
Holding onto grudges against people who have wronged you can cause you unnecessary stress. It is okay to feel angry at first, but after a while, you need to let it go. Forgiving someone doesn't mean that you are saying that they weren't wrong, or that you have to keep them in your life, but it will unburden you from any bad feelings and allow you to move on.
Reflect on the good things
Reflecting on the good things in your life, that you are thankful for is an excellent way to bring you out of your slump. You can sit and try and write a list of a few good things that have happened in the past, to remind yourself that things won't always be bad.
If you want to preempt this, you could start writing a list of gratitude when good things happen, even little things, like seeing a cute dog, that you can then look back on when you are feeling down.
Do something you love
Carving out time to do something that you love will help you to feel happier. If you are just always working and doing things for other people, then it is not surprising that you feel down. You need to have an outlet for yourself, where you can develop your hobbies, or just have a bit of fun. It could be that you go to a dance or martial arts class once or twice a week. You could also paint or knit. It doesn't matter what you do as long as you love it.
Learn about peace
Peace is something that many imagine a lot. Whether it is peace in the home or peace in the world, it is something that people are always searching for. You can have peace in your own life by making time for yourself through meditation or doing something you enjoy.
Peace on a larger scale can be more challenging to think of, but you can listen to positive messages spread by speakers like Prem Rawat, who has inspired many people to discover and practice peace.
