^^^ I'm a fervent, evangelical proponent of "You get just the one life, so LIVE IT!!!" Obviously, don't overextend yourself financially, but if there's a way you can afford it, and you're just balking at the price as some abstract large amount...oh, just do it and go!
It's a cliche, but you rarely regret the things you did, and you nearly always regret the things you did not.
So true - as you've said as long as you don't over extend yourself financially and travel within budget, there's no need to look back at the cost and overall money spent on travel. I think I've only totted up how much I spend on travel when I was doing a household budget one time, and I swiftly put an end to doing that! If I know I can afford it, I just book it. I just think of the amazing time I'll have and that this is my life to live.
If I find I'm trying to talk myself out of spending that much on travelling, I imagine myself in a nursing home when I'm old and the possible regrets I might have; I know if I don't travel when I can and want to I'll regret it. Life and circumstances can change and you just have to do it when you can.
This May it'll be a round trip of Croatia, Montenegro, Serbia and Bosnia, then New York in October for me - roll on!!
Work to live not the other way around
