All of us go through a lot of struggles, tests, and hardships in life. Do not compare nor discriminate against others based on their life experiences because you don't know what they're going through and what they've been through to get there. Be proud and share love to all and it will come back to you. 

By living peacefully, you must put yourself on someone else's shoes and feel what they feel because everybody has their own mission and own journey to accomplish it.  No matter how long it takes, trust your will, your capability, and you can do it. Always continue to inspire and never let anyone tell you that you can't do it.
