The first one.

It's very difficult to write English after years of not using this language. I had been learning English for a long time, but my knowledge isn't satisfying. Now, when I don't have to learn, I'm more motivated than in the past.

I should probably introduce myself - my name is Paulina. Now I'm full time mum of two little children. My daughter is 2 years old and my son is 5 months. He is waking me up a few times every night (I really hate that part of parenthood). Every day is full with playing around with the children, cooking, cleaning, etc. The weird thing is, afterwards I have more time for learning than I had in school.

I like technology, computers and everything that is useful and can make our life easier. My passion is programming (I'm programmer). In my free time I love to juggle, to hike and spend time close to nature.

Thank you for taking the time to read this. I would be grateful for every correction that you made. Have a great day!

*****Paulina....do you juggle or jog? (running)

It's very difficult to write English after years of not using the language. I had learned English for years, long ago, but now my knowledge level isn't satisfactory. Now that I don't have to learn, I'm more more motivated.

I should probably introduce myself. My name is Paulina. I'm now a full time mum with two little children. My daughter is 2 years old and my son is 5 months old. He is still waking me up several times every night(I really hate that part of parenthood). Every day is full of playing, cooking, cleaning and more. A weird thing is that now I seem to have more time for learning than I had while I was in school.
