What shall I do?

I am currently thinking about my further study. I do not have to work, because so far my husband's income is enough for two of us if we would not go for traveling around. And I do not care for traveling much.

Yesterday I talked with my friend on the phone. She is now 35 and thinking about back to study keenly. However, to her, her age is the problem. Because her ideal life plan is get married with somebody else and give birth during 30s'. So she does not really want go to three years course. After the course she will be 38, and will perhaps miss the chance. But she also cannot stay to do nothing. So she is looking for a short course. She has financial problem too, so I introduced her to some scholar ships. She is interested in paramedic course and psychology course. 

Today I talked with a young teacher aid. She is pregnant now.
She used learn at the fashion course for two years, but she has not done a relative job. And she said that she used student loan and it is still painful to give it back. I thought that she does not do fashion work is really shame.
She said that she has to work. And now she is doing teacher aid course by correspondence. I told her about my thought, so she asked me "What course do you want to do?" I said "I have not decided yet."

I also finished two years nursing course in Japan, but I left the job for a long time ago and I was not very interested in nursing. However I am always thinking I want to do a work that relate to nursing job, but not physical job, office type of job. Because since I worked in the hospital, I was interested in a job that is support people between hospital to home, a kind of management job or planner. To get the job, I need to improve my English skills more.

I also need to take a examination to get into any course here, because English is my second language. My friend, above, she has overall 6.5 IELTS score,but I have not taken the exam yet, and I think my score would be below 6. That is why I am learning writing.
