If your heart is telling you that you would be happier with another major, you should probably listen to it. I changed my major twice and have zero regrets. I can't imagine going through life employed in the field of my first major. Don't listen to the people telling you to stay. It is your life, not theirs. Make the switch and don't look back.

K P :

my major now is engineering, and 'another major' I wanna take doesn't has anyrelation with engineering, it's about social, counseling. and when I tried to tell about it, people told me that I will get job with my engineering degree and my 'social' degree in counseling won't help me in financial. the point is the degree I wanna take is useless and will be in vain (is it correct grammar?)

but, in counseling I find my self who never get tired or boring at all. it's like I full of power inside and I don't know where from I get the the big spirit. I just feel my soul is complete as a human. That's all. But if I take it, I really feel be selfish one. people around me, they expect too much.

Walter_mellon:

thank you very very much! You give me a lot spirit and make me believe more about my decision. in fact, you support me.

I have difficult choices. if I don't change my major, absolutely I know I won't live happily in all my life, but if I change, I will be so selfish for people around me because they expect too much.

thank's walter :)

Aya, I don't know how sincere you are, but the way you've put it -  you just have no other choise.
But there're still a couple of important questions.
What is your major now and what 'another major'  you're talking about? Why wouldn't you find 'the people who support'??

Well, a lot of my friends (I'm not an exception) either changed their specialties or have two degrees:)
In some developed countries education is pretty long process. Sometimes it's completed somewhere well in your 30's.
