A bad habit

I have a bad habit. A very bad indeed.

It is whenever Once I started on something I refuse to let it go;

When I learn to love someone who does not feel the same, it takes forever for me to move on.
but I did

When I proclaimed a friend to be my best friend, I prevent her from having others as her best friend.
in the end she left

When I join Navy and found out that it is too much for my limit, I stubbornly stay put and wade through it all.
I was able to reach beyond

whenever a task gets too difficult, I tried to run but I always found myself facing it head on.
and finish it

now, when I think I have made a mistake of choosing someone as my guide, I will never change the path I had chose and stick to this guide no matter how hard the road I walk on.
this guide might not be the most ideal guide I imagine and I already felt more lost than ever with her guidance
but,
I refuse to change side because I was the one who chose her in the first place.
maybe I'll get lost more and more in the jungle of confusion and uncertainty
but,
at least I know I will not lose the faith I have in you.

so, please guide me well, teacher.
