I really admire your determination in planting. Like what you said about Thomas Edison, that you've found a thousand ways to prevent seeds from germinating in hostile climates. - this is a great lesson we can have once we are determined in one thing just like planting. We may face many challenges but never give up, instead, learn from it and make sure to continue and apply what is needed to do. Just like experiment in science. If you gave up you will not see the best output or outcome. Just like in real life situation, as we grow older we are learning from the experiences and challenges came to our life, once we overcome those challenges we can just laugh at them and say's "I did it and I'm stronger now!"
