LNY, I agree with you in the main, but wanted to take exception to this.^^It's impossible not to,sadly.
Focus on the loss, and you will undoubtedly make yourself sad. To even use the term "loss", though, is framing the situation in a way that's guaranteed to be unpleasant.
Think cost/benefit, instead (so "cost" instead of "loss"). Everything we do in life has costs and benefits. On another thread I made some "circle of life" comments, and they apply here. We move into a new house: It's temporarily sad to leave the old home with all its memories, but we are moving on to new adventures and new memories. Our children grow and leave the house: It's a kind of 'loss' or 'sadness' to know that a chapter is ending, but a new chapter is beginning, and the change is worth it (in addition to being inevitable).
If we believe Paul, then everything other than the knowledge of Christ is "loss", but loss in the same way you "lose" the garbage you take out (see Phil 3:8). We also know that all things work together for our good (see Rom 8:28), right? And then there's the pearl of great price, and the treasure in the field, etc.
So if you're stuck focusing on what you're "losing" or "giving up", then maybe you need to revisit the basics and refocus on what you're gaining that is worth so much more than what you're being asked to pay for it.
