Sorted seeds out

Finally sat down and sorted seeds out for each month of sowing,going on past years I didn't take much notice. I know the dates are a guide line only  so I've always used that sown early,will try and hold back a little longer this year. I could move to warmer parts of the country  and sow early then move back once we have growth,or sneak the seeds in the conservatory or near the windows. I have more luck winning the lottery than sowing seeds in the house,end of the day if sow early I may lose a few plants and most of them will take time to grow. I may just wait and do them once it get warmer and the right time,I'll only get upset If I start early and lose them all. Just need to relax and chill out.
