I read the following on bitcoin.org

A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.

Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.

Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.

In some ways it sounds like they are describing mining when they say "validating those transactions and blocks", but I also believe running a full node is different than mining. In what way is running a full node help the bitcoin network? Does it just help transfer information about transactions that have been processed by miners?

If running a full node is in fact distinct from mining, what incentive do people have to run full nodes if they aren't able to earn the reward as a miner would. Is it just for bitcoin supporters who want to help bitcoin grow?

Incentives to run and use a bitcoin full node:

  1. Not trusting anyone, verifying everything.

  2. Privacy. Not sharing information about your transactions with others.

  3. Enforce consensus rules.
