Out of interest how many vlogs of daily vloggers are you watching currently???
I used to watch Pewdiepie's vlog when he did a daily vlog and I enjoyed it.
These days I'm working my way through Casey Niestat's vlogs. He's a real inspiration for me and what made me consider vlogging in the first place. (totally look up his channel) He's been doing a daily vlog for the better part of a year and does say he loses a lot of sleep just cause editing takes so long.
Firstly, make sure you want to make daily vlogs because you want to. I find the best daily vloggers of small channels are ones that daily vlog because they want to document their lives for themselves.
Maybe daily/weekly vlogging could have an effect on your lifestyle and push you to do more interesting things? That is a positive in itself!
I have a bunch of personal reasons to may the vlogs, the three most prominent ones being,
1) Having a more exciting life like you said, (having the guts to go talk to someone i wanted to talk to under the guise of an interview or having a 'work' related excuse to go to an interesting place)
2) My memory really really sucks about my own experiences, so vlogging is as much for myself as everyone else.
3) I'm a creative, but a perfectionist. Often I get scared to create things for fear they won't live up to my expectations. But daily or regular vlogging are only a one day thing, and tomorrow you have another go. There's not much time to sit and dwell and demoralise myself, just keep working.
