Life Hacks To Effectively Boost Your Self-Esteem
Show More Kindness Towards Others

Sounds easy right? For others, it may pose more of a challenge. When you show kindness towards others on a daily basis, you too will begin to treat yourself with more kindness as well. Just like the golden rule states 'treat others the way you would want to be treated,' as how you treat people is often how they will treat you in the long run. Some ideas include just being there to listen to someone as they vent, encourage somebody when they are discouraged from reaching a goal, or help someone out when you notice they are in distress.
You can set the tone of your day by staying consistent with your kindness by complimenting someone first thing in the morning, engaging with people individually and giving them your utmost attention, holding the door for someone, or simply using 'please' and 'thank you' whenever someone does something for you. It's a pretty simple concept but can make a significant impact on your mental health and your relationships with those around you.
Get Out Of Your Comfort Zone

When you step out of your comfort zone and try something new, you're challenging yourself to improve your skills and become a better version of yourself, which directly impacts your opinion of yourself for the better. Even if you don't do too well at it, you still tried something different rather than sticking to the same old routine you know, which is something to truly admire and appreciate about yourself.
Whether it's training for a marathon or taking up a new hobby like learning how to play an instrument, whatever it may be, bursting out of your confined bubble will give your confidence a healthy boost. It also allows you to learn more about yourself and what skills and abilities you are capable of. Picking up a new hobby can also be incredibly fulfilling and give you a sense of satisfaction like no other. Try to get out of your comfort zone regularly, with zero expectations, and just tell yourself to try something new.
