This is the only real "investment" that pays off in your life!
Never stop investing in yourself, no matter who you're with, how much you're loved, or how much you've achieved. Don't suppress your needs or desires because you're afraid of how people will perceive you or judge you. Do your best to always be "enough for yourself" without needing the approval of others, without needing their pats on the back! First, YOU have to be your own motivation, only then can others motivate you. Sometimes you simply won't find the support you're looking for in others, but you will always, always, find it in yourself!
Never forget to protect yourself from those who want to tear you down, hurt you, make you feel like you're not good enough. Always protect yourself from those who underestimate everything you do: your work, talent, passion, hobbies. Don't let their opinions take up too much space in your head and let their view of you be your mirror! Protect yourself from those who have never lived a day in your shoes, but still feel they have the right to tell you what you should and shouldn't do. Protecting yourself from those who pretend to care about you but really don't know what makes you happy. From those who try to overshadow you every time you truly shine.
Never stop believing in love, but learn to be content with being alone. Don't try to settle just because your biological clock is ticking. Don't stay too long with someone who doesn't appreciate and respect you. Walk away when you see a pattern that doesn't change. Walk away from someone who only brings out the worst in you, because love should only bring out the best in you.
Never stop investing in yourself, no matter how busy or overwhelmed you are. Honestly, at the end of the day, you only have yourself! It is difficult to predict where life will take those you love. They may suddenly decide to pursue other things or move elsewhere. People will always follow what makes them happy, they will always do what is best for them, and you should always be ready for that. Ready for moments when you will be alone, for moments when you will feel that you have no one by your side, that no one is on your side. Prepare for the moments when you will need all your strength and tenacity, and no one else can give it to you!
Invest in yourself because it is worth all the time, money and effort in the world. Invest in yourself, because this may be the only relationship that is guaranteed in your life. The return on this investment will ALWAYS pay off!
