Ideas to have a better year. If you can, correct me, please!

Last year, I did some of things to improve my life. For instance, I went to a gym
(I keep going there now). Secondly, I changed my diet to feel better, I eat a lot of vegetables, fruits,etc.and I try not to eat fatty/grease food .( I don't know).

Last month, I went to a fantastic house up the mountain, because sometimes we need to forget, and don't need to think about job matters, or other problems we may have.
This year, I will go on doing these things. But probably, I'll have to use my car occasionally, since it´s harmful for the environment.
I have started to teach maths. My neighbours´son needs help with it, and why I don't accept his request?
I think I should get some money for the poor.

What about you? What do you need to have a better year?

I'm looking forward to your answer!

Last year, I did something to improve my life. For instance, I went to the gym ( at this moment, 
I go on to go to the gym). Secondly, I changed my diet to feel better, I ate a lot of vegetables, fruits...and I tried not to eat fatty food. (Use Past Simple because these events were in the past - last year) 

Last month, I went to a fantastic house in the mountains because sometimes you need to forget and  not to think about the job or other problems. 
This year, I will go on doing these things. But probably, I must not use so much my car because it´s not good for the environment. 
I have started to teach Maths. My neighbours´son needs help with it, and why not?
I think I should give some money for poor people. 

What about you? What do you need to have a better year?

I look forward your answer!

This year, I will go on doing these thing, but probably, I must not use my car so much as it´s not good for the environment.

I think I should take some money to poor people.

What about you? What do you require to have a better year?

Last year, I did some things to improve my life. For instance, I went to the gym (at this moment,
I'm go online at the gym). Secondly, I changed my diet to feel better. I ate a lot of vegetables, fruits etc. and I tried not to eat fatty/greasy food. ( I don´t know).

"I'm online at the gym". If you're just saying where you are, just say "I'm at the gym." If you're saying you're heading towards the gym, say "I'm going/heading to the gym".

'Some thing' is an example of two words which are conventionally written as one... for some reason. To pluralise it you need to split it first.

I'm confused about what you don't know.

I think I should collect some money for poor people. or I think I should give some money to poor people.

"...you need to ...and you need to..." You don't need to say 'need to twice'. You could just say "sometimes you need to forget and to..."

Either "collect" for them (on their behalf) or "give to" them. To do something for someone/something is to do it on their behalf.

What about you? What do you need to have a better year?

I look forward your answer!
