    websites for about a year and ɑm ϲoncerned about switching to another platfⲟrm.

    I have heaгd ɡreat things about

    Is there a way I can imρort all my wordpress posts into it?

  2. Hi! I understand this is sort of off-topic however
    I had to ask. Does running a well-established blog like yours require a large amount of work?
    I am completely new to blogging however I do write in my diary every day.
    I’d like to start a blog so I will be able to
    share my personal experience and views online.
    Please let me know if you have any kind of recommendations or tips
    for brand new aspiring bloggers. Thankyou!

  3. First of all I want to say fantastic blog! I had a quick question which
    I’d like to ask if you do not mind. I was interested to know
    how you center yourself and clear your head before writing.
    I have had a hard time clearing my mind in getting my thoughts out.
    I do take pleasure in writing however it just seems like the first 10 to 15
    minutes are usually lost just trying to figure out how to begin. Any recommendations or hints?
    Thank you!
