The truth about permanent markers
Nothing in this life is permanent.
Whenever you judge the way you speak or how your voice sounds, remember that your judgements are temporary.
You are not stuck with the way you sound. Your voice is just a series of habits that you've ingrained over time unconsciously. And remember that habits can be changed!
Don't be so attached to who you are in the present that you don't give the future version of you a chance!
