(Excuse me while I get on my soapbox. But this one I can't resist or hold in.)
Some people will never know what it is to truly fight to get something in life. Some people get many "things" handed to them easily, and take those things for granted, not even giving them the appreciation they deserve. This goes for jobs, spouses, parents, siblings, cars, homes, financial handouts, and nearest and dearest to my heart, children.
These things are not rights people!
They are privileges!
You are not guaranteed to get them nor to keep them. Appreciate what you have.
Stop taking them for granted, for tomorrow may not come and if it does for you, it may not for others around you. And I am no saint... far from it. I complain far too often and I am first to admit that. But the things we complain about... someone somewhere would give anything to have. And that someone is probably far closer than you realize.
Infertility has taught me a LOT of hard lessons. This is, without a doubt, in the top 3 lessons learned so far in this journey. Going through this, learning these hard lessons... it has really helped my consideration for others and the (often silent) things they may be going through to grow and be strengthened.
