Sometimes I feel frustration at the bureaucracy for not moving fast enough to deliver in the way that I would prefer. But that is probably because I have worked for many years in the civil society, which tends to move much faster than government.

For me, one of the major reasons to move beyond just the planting of trees was that I have tendency to look at the causes of a problem. We often preoccupy ourselves with the symptoms, whereas if we went to the root cause of the problems, we would be able to overcome the problems once and for all.

Using trees as a symbol of peace is in keeping with a widespread African tradition. For example, the elders of the Kikuyu carried a staff from the thigi tree that, when placed between two disputing sides, caused them to stop fighting and seek reconciliation. Many communities in Africa have these traditions.

It's very important to remain optimistic and to see the silver lining in everything you do. Because no matter how sometimes things look difficult, and look like there is no hope, there is always a small glimmering of silver lining that is in everything, and I always look for that, and hang on that, and before I know it, another day comes and is gone.

When I first started, it was really an innocent response to the needs of women in rural areas. When we started planting trees to meet their needs, there was nothing beyond that. I did not see all the issues that I have to come to deal with.

Those of us who witness the degraded state of the environment and the suffering that comes with it cannot afford to be complacent. We continue to be restless. If we really carry the burden, we are driven to action. We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!

You can make a lot of speeches, but the real thing is when you dig a hole, plant a tree, give it water, and make it survive. That's what makes the difference
