How to enjoy life? There are many ways to enjoy life. You can take your dog for a walk, plant a tree, learn a new language or even go shopping. It merely depends on what you prefer to do and how would you react to a given situation. Remember that all problems has a lot of possible solutions.
Now back to the question, enjoying is like living your life to the fullest. It's like living your last day today, your last hour, your last minute, your last second. Anyway, of all the resources that we have, it is time that can not be recovered. Like they always say, "Time will not wait for us."
Given the circumstance, I think the most appropriate question for this is how will we make our life meaningful? If I'm going to answer it, maybe it is all about doing something that you love, something you're passionate about and devoting yourself to it. It includes letting our self-centeredness out of our mind and out of our heart. For this would only cause envy, jealousy and others nasty things that we could think of. I know that it is not easy to do it and sometimes we can't help it because as they say, "self-centeredness is a part of human nature". But if we begin to compare ourselves to others, knowing that though this may sometimes work to improve oneself, later on our self-centeredness would also be the cause of our destruction.
Enjoying life is all about giving and receiving. Accepting one's strength and weakness and always strives for the better. As much as we want to be respected, we also give respect. We should also respect the dignity and the rights of others. We continue to struggle for our shortcomings.
It's all about having a positive mental attitude and working with action. I know that it is better said than done but we should always look forward to the brighter side of life no matter how worst the situation there is.
