My journey to learnmaster English

This is a bit nitpicky, but when you say "my journey to... ", what follows should be the goal. To learn English can mean to study English, rather than to become good at it. You're not journeying to eventually get to your desk and open a textbook, you're journeying by studying/learning, and your goal is to speak well.

My journey to master English
My journey in learning English
My English learning journey

These sound better to me.

But it's a nitpick, if this didn't make sense to you, don't worry.

In tThese days l, I'm learning English l have a pand I'm having troublem with Englishit.

I must learn it because i want it to help me in my work (or at work - more common and a bit less specific) and my relationship.
