Summarize the main points in the text below - 

You'll always want to have access to sufficient emergency funds for, well, emergencies. Make sure you can afford a health emergency (some insurance plans require you to pay first and claim for reimbursement later), a one-way ticket home in the event that something urgent happens, a missed flight, or a theft or unexpected mishap. And, more practically, you may find that you've under-budgeted and you need to increase your budget a bit while you're on the road, so having access to some emergency cash might prevent you from having to cut your trip short or miss out on things you wanted to see.

In short, you need to be able to afford to get yourself out of bad situations if you really have to. Remember that as a solo traveler you will generally not have another person readily available to help with bad situations, so it's up to you to be able to manage them.

It's a good idea to have a variety of different sources of emergency funds, including cash in hard currencies like US dollars or Euros, a credit card (and backup) with a decent limit, and a trusted friend or relative back home who can send you money in an emergency.
- Have money set aside for emergencies like health issues or an emergency trip home
- Budget enough to get yourself out of unexpected situations if needed
- Remember, if you’re by yourself you will be the one managing any problems
- Carry a few different ways to pay for things if needed like cash and credit cards, and  have someone to borrow from back home if needed
