At your absolute best, you'll still won't be good enough for the wrong person. At your worst, you'll still be worth it to the right person.
The best feeling in the world is knowing that both your presence and absence means something to someone.
It sucks when the people who you thought you knew starts becoming the strangers you never wanted.
That's the problem with putting others first; you've taught them you come second.
Do not chase people, be you and do your own thing and work hard. The right people who belong in your life will come, and stay.
