Oh gosh, the list is endless.. you maybe are suffering from writers block - hopefully only temporary.. but here's a few suggestions maybe.. and please forgive if any or all are not suitable.. I've never read or written a blog really.. I had some stuff on here under my old profile but that would all be gone now..
The younger generation and how you think and feel about them? Human rights? Spirituality and finding one's own way Our thoughts and feelings and what makes us that way? Our responses to our family when they are irritating, A course or hobby we have just taken up pets and their behaviour and place in our lives Work colleagues and their behaviours/office politics
Oh dear I could go on and on so should leave it at that now..
I think its really just meant to be about you and how you think and feel and react to things that happen in your every day life.. including things you read and see on tv
Write about animals which are no longer on the endangered list and how that feat was achieved with human intervention. Of course, there's research to do.
Write about technology and the damage it is doing to your generation.
Write about the virtues of eating a big variety of pure foods including sweets and how ceasing this common sense approach in the 50s/60s and investing in the weight-loss-and-beauty-for-a-fee movement has caused much of the major health problems of today.......including depression and anxiety.
Write about being appropriate. What does that look like?
