If you used to with like, it would be better not to use a gerund in the second clause.
So,it's better to say: 'I like walking alone, thinking about many things.'
or to be more accurate: 'I like walking alone while thinking about many things.'

I'm just expressing my thoughts by writing them here
And 'I have nothing to write about,' sounds more accurate.

Everything is one word; don't separate it into two words

And it's better to say:
In winter, everything seems quiet
or:
Everything seems quiet in winter.

I think you better revise that sentence which is marked with red.
I don't know why, but it doesn't sound quite right.
